DWGPIO(4)

💅 DWGPIO(4) — like, the Synopsys DesignWare GPIO controller, bestie ✨

okay so this is a page from the Kernel Interfaces Manual (that's the section 4 girlies, iykyk) and it's all about dwgpio — one specific driver, and honestly she's short but she serves. 🎀

✨ SYNOPSIS ✨

dwgpio* at acpi?

that's it. that's the whole config line. iconic minimalism. 🦋

🌸 DESCRIPTION 🌸

okay so the dwgpio driver is out here providing support for the Synopsys DesignWare GPIO controller — and before you ask, yes, that's a real thing, and yes, you'll find it on stuff like the Ampere eMAG SoC. 🔥

here's the thing though, and this is lowkey important: dwgpio does not provide direct device driver entry points. nope, not her job. instead, she makes her functions available to acpi(4). it's giving backstage-pass energy — she's not the main character on stage, she's the one making sure the main character works. 🫶
